T0 ALL WHOM IT MAY CONCERN:

Be it known that I, J. A. MARVIN, of Red Wing, Goodhue county, Minnesota, have invented a. new and useful Improvement in Hea- :ers and I do hereby declare that the following is a full, clear, andi-exact description thereof, which will enable those skilled in the art to make and use the sume, referencewb'eing had tothe accompanying drawings, forming part ot' this specification.

Figure 1 is a sectional elevation ofthe stove with the drum attached, it being through' the line of iig. 3. Figure 2 is a horizont-al section through the line a: a: of tig. 1. i

Figure 3 is u top view.

Similar letters of reference indicate corresponding parts.`

A represents the stove proper. B is the door for the introduction of fuel. C is the stove-drum. vD is the vcasing or radiator, which is placed around the drum and the iiues which connect the drum with the stove. E

is the evuporating-vessel. Fis an aperturethrough the drnmin the top of which E is pla-ced. The smoke and heated' gases are conducted into the drum by the ues hifi-om which they pass into the smoke-flue H, through the short pipe J direct, or are made to descend through a diving-fine, Jf, seen in fig. 2, andere con ducted into the smoke-pipe H by the short4 pipe z', the direction of*` the smoke being governed by a domper in the pipe H at k. The euseV or radiator D rests on the top of the stove-plate at l, the lower end of which is out and perforated for the purpose of admitting air frolnthe surrounding air in the room. m is-a tube, which is,

connected with the case D at its upper end, as seen in vthe drawing, the other end of which niay extend through the ioor and to the outside of the house for the purpose of co'nducting a current of fresh air within. the

casing. The air which enters the ca'sng, and is warmed by the flues and drum, is'discharged through the pipes 'n n, and through a register, seen at o, in the centre of the case.. The air which is discharged through the vregister enters `the room; that Vwhich passes through the pipes n n, or either of' them, may also be discharged into the room where this stove is, or be conducted by air-pipes to other rooms in the house, us may be desired. All the air which passes from thecasing is-mostened by the vapor which rises from the water in the evaporatingvessel E, and the direction ot' thc air is controlled by dampers in the pipes n n, and by the register at o.

What I claim as new, and desire to secure by Letters Patent, isy 1. The evaporating-vesselE, suspended in the central opening F of the drum C by uieitns of a rod from the top of the drum, said rod hearing the register, as herein described for the purpose specified'.

2. The arrangement of the annular drum C, supported Within the radiator D by the pipes g,` said radiator resting upon the stove A, driving-flue J, pipe H, tube m, evaporating-vessel E, register O, and hot-air pipes n,

as herein shown and described.

The above specification of my invention signed .by me, this 22d day of April, 1867.
